      ARM: mvebu: fix overlap of Crypto SRAM with PCIe memory window · d7d5a43c
      Thomas Petazzoni authored
      When the Crypto SRAM mappings were added to the Device Tree files
      describing the Armada XP boards in commit c466d997 ("ARM: mvebu:
      define crypto SRAM ranges for all armada-xp boards"), the fact that
      those mappings were overlaping with the PCIe memory aperture was
      overlooked. Due to this, we currently have for all Armada XP platforms
      a situation that looks like this:
      
      Memory mapping on Armada XP boards with internal registers at
      0xf1000000:
      
       - 0x00000000 -> 0xf0000000	3.75G 	RAM
       - 0xf0000000 -> 0xf1000000	16M	NOR flashes (AXP GP / AXP DB)
       - 0xf1000000 -> 0xf1100000	1M	internal registers
       - 0xf8000000 -> 0xffe0000	126M	PCIe memory aperture
       - 0xf8100000 -> 0xf8110000	64KB	Crypto SRAM #0	=> OVERLAPS WITH PCIE !
       - 0xf8110000 -> 0xf8120000	64KB	Crypto SRAM #1	=> OVERLAPS WITH PCIE !
       - 0xffe00000 -> 0xfff00000	1M	PCIe I/O aperture
       - 0xfff0000  -> 0xffffffff	1M	BootROM
      
      The overlap means that when PCIe devices are added, depending on their
      memory window needs, they might or might not be mapped into the
      physical address space. Indeed, they will not be mapped if the area
      allocated in the PCIe memory aperture by the PCI core overlaps with
      one of the Crypto SRAM. Typically, a Intel IGB PCIe NIC that needs 8MB
      of PCIe memory will see its PCIe memory window allocated from
      0xf80000000 for 8MB, which overlaps with the Crypto SRAM windows. Due
      to this, the PCIe window is not created, and any attempt to access the
      PCIe window makes the kernel explode:
      
      [    3.302213] igb: Copyright (c) 2007-2014 Intel Corporation.
      [    3.307841] pci 0000:00:09.0: enabling device (0140 -> 0143)
      [    3.313539] mvebu_mbus: cannot add window '4:f8', conflicts with another window
      [    3.320870] mvebu-pcie soc:pcie-controller: Could not create MBus window at [mem 0xf8000000-0xf87fffff]: -22
      [    3.330811] Unhandled fault: external abort on non-linefetch (0x1008) at 0xf08c0018
      
      This problem does not occur on Armada 370 boards, because we use the
      following memory mapping (for boards that have internal registers at
      0xf1000000):
      
       - 0x00000000 -> 0xf0000000	3.75G 	RAM
       - 0xf0000000 -> 0xf1000000	16M	NOR flashes (AXP GP / AXP DB)
       - 0xf1000000 -> 0xf1100000	1M	internal registers
       - 0xf1100000 -> 0xf1110000	64KB	Crypto SRAM #0 => OK !
       - 0xf8000000 -> 0xffe0000	126M	PCIe memory
       - 0xffe00000 -> 0xfff00000	1M	PCIe I/O
       - 0xfff0000  -> 0xffffffff	1M	BootROM
      
      Obviously, the solution is to align the location of the Crypto SRAM
      mappings of Armada XP to be similar with the ones on Armada 370, i.e
      have them between the "internal registers" area and the beginning of
      the PCIe aperture.
      
      However, we have a special case with the OpenBlocks AX3-4 platform,
      which has a 128 MB NOR flash. Currently, this NOR flash is mapped from
      0xf0000000 to 0xf8000000. This is possible because on OpenBlocks
      AX3-4, the internal registers are not at 0xf1000000. And this explains
      why the Crypto SRAM mappings were not configured at the same place on
      Armada XP.
      
      Hence, the solution is two-fold:
      
       (1) Move the NOR flash mapping on Armada XP OpenBlocks AX3-4 from
           0xe8000000 to 0xf0000000. This frees the 0xf0000000 ->
           0xf80000000 space.
      
       (2) Move the Crypto SRAM mappings on Armada XP to be similar to
           Armada 370 (except of course that Armada XP has two Crypto SRAM
           and not one).
      
      After this patch, the memory mapping on Armada XP boards with
      registers at 0xf1 is:
      
       - 0x00000000 -> 0xf0000000	3.75G 	RAM
       - 0xf0000000 -> 0xf1000000	16M	NOR flashes (AXP GP / AXP DB)
       - 0xf1000000 -> 0xf1100000	1M	internal registers
       - 0xf1100000 -> 0xf1110000	64KB	Crypto SRAM #0
       - 0xf1110000 -> 0xf1120000	64KB	Crypto SRAM #1
       - 0xf8000000 -> 0xffe0000	126M	PCIe memory
       - 0xffe00000 -> 0xfff00000	1M	PCIe I/O
       - 0xfff0000  -> 0xffffffff	1M	BootROM
      
      And the memory mapping for the special case of the OpenBlocks AX3-4
      (internal registers at 0xd0000000, NOR of 128 MB):
      
       - 0x00000000 -> 0xc0000000	3G 	RAM
       - 0xd0000000 -> 0xd1000000	1M	internal registers
       - 0xe800000  -> 0xf0000000	128M	NOR flash
       - 0xf1100000 -> 0xf1110000	64KB	Crypto SRAM #0
       - 0xf1110000 -> 0xf1120000	64KB	Crypto SRAM #1
       - 0xf8000000 -> 0xffe0000	126M	PCIe memory
       - 0xffe00000 -> 0xfff00000	1M	PCIe I/O
       - 0xfff0000  -> 0xffffffff	1M	BootROM

      Pull xfs fixes from Dave Chinner:
       "This is a fix for a regression introduced in 4.5-rc1 by the new torn
        log write detection code.  The regression only affects people moving a
        clean filesystem between machines/kernels of different architecture
        (such as changing between 32 bit and 64 bit kernels), but this is the
        recommended (and only!) safe way to migrate a filesystem between
        architectures so we really need to ensure it works.
      
        The changes are larger than I'd prefer right at the end of the release
        cycle, but the majority of the change is just factoring code to enable
        the detection of a clean log at the correct time to avoid this issue.
      
        Changes:
      
         - Only perform torn log write detection on dirty logs.  This prevents
           failures being detected due to a clean filesystem being moved
           between machines or kernels of different architectures (e.g.  32 ->
           64 bit, BE -> LE, etc).  This fixes a regression introduced by the

      drm/i915: Actually retry with bit-banging after GMBUS timeout · 0bbca274
      Ville Syrjälä authored
      After the GMBUS transfer times out, we set force_bit=1 and
      return -EAGAIN expecting the i2c core to call the .master_xfer
      hook again so that we will retry the same transfer via bit-banging.
      This is in case the gmbus hardware is somehow faulty.
      
      Unfortunately we left adapter->retries to 0, meaning the i2c core
      didn't actually do the retry. Let's tell the core we want one retry
      when we return -EAGAIN.
      
      Note that i2c-algo-bit also uses this retry count for some internal
      retries, so we'll end up increasing those a bit as well.

      [media] media-device: map new functions into old types for legacy API · b2cd2744
      Mauro Carvalho Chehab authored
      The legacy media controller userspace API exposes entity types that
      carry both type and function information. The new API replaces the type
      with a function. It preserves backward compatibility by defining legacy
      functions for the existing types and using them in drivers.
      
      This works fine, as long as newer entity functions won't be added.
      
      Unfortunately, some tools, like media-ctl with --print-dot argument
      rely on the now legacy MEDIA_ENT_T_V4L2_SUBDEV and MEDIA_ENT_T_DEVNODE
      numeric ranges to identify what entities will be shown.
      
      Also, if the entity doesn't match those ranges, it will ignore the
      major/minor information on devnodes, and won't be getting the devnode
      name via udev or sysfs.
      
      As we're now adding devices outside the old range, the legacy ioctl
      needs to map the new entity functions into a type at the old range,
      or otherwise we'll have a regression.
      
      Detected on all released media-ctl versions (e. g. versions <= 1.10).
      
      Fix this by deriving the type from the function to emulate the legacy
      API if the function isn't in the legacy functions range.

      KVM has special logic to handle pages with pte.u=1 and pte.w=0 when
      CR0.WP=1.  These pages' SPTEs flip continuously between two states:
      U=1/W=0 (user and supervisor reads allowed, supervisor writes not allowed)
      and U=0/W=1 (supervisor reads and writes allowed, user writes not allowed).
      
      When SMEP is in effect, however, U=0 will enable kernel execution of
      this page.  To avoid this, KVM also sets NX=1 in the shadow PTE together
      with U=0, making the two states U=1/W=0/NX=gpte.NX and U=0/W=1/NX=1.
      When guest EFER has the NX bit cleared, the reserved bit check thinks
      that the latter state is invalid; teach it that the smep_andnot_wp case
      will also use the NX bit of SPTEs.

      KVM: MMU: fix ept=0/pte.u=1/pte.w=0/CR0.WP=0/CR4.SMEP=1/EFER.NX=0 combo · 844a5fe2

      Yes, all of these are needed. :) This is admittedly a bit odd, but
      kvm-unit-tests access.flat tests this if you run it with "-cpu host"
      and of course ept=0.
      
      KVM runs the guest with CR0.WP=1, so it must handle supervisor writes
      specially when pte.u=1/pte.w=0/CR0.WP=0.  Such writes cause a fault
      when U=1 and W=0 in the SPTE, but they must succeed because CR0.WP=0.
      When KVM gets the fault, it sets U=0 and W=1 in the shadow PTE and
      restarts execution.  This will still cause a user write to fault, while
      supervisor writes will succeed.  User reads will fault spuriously now,
      and KVM will then flip U and W again in the SPTE (U=1, W=0).  User reads
      will be enabled and supervisor writes disabled, going back to the
      originary situation where supervisor writes fault spuriously.
      
      When SMEP is in effect, however, U=0 will enable kernel execution of
      this page.  To avoid this, KVM also sets NX=1 in the shadow PTE together
      with U=0.  If the guest has not enabled NX, the result is a continuous
      stream of page faults due to the NX bit being reserved.
      
      The fix is to force EFER.NX=1 even if the CPU is taking care of the EFER
      switch.  (All machines with SMEP have the CPU_LOAD_IA32_EFER vm-entry
      control, so they do not use user-return notifiers for EFER---if they did,
      EFER.NX would be forced to the same value as the host).
      
      There is another bug in the reserved bit check, which I've split to a
      separate patch for easier application to stable kernels.

      s390/mm: four page table levels vs. fork · 3446c13b
      Martin Schwidefsky authored
      The fork of a process with four page table levels is broken since
      git commit 6252d702 "[S390] dynamic page tables."
      
      All new mm contexts are created with three page table levels and
      an asce limit of 4TB. If the parent has four levels dup_mmap will
      add vmas to the new context which are outside of the asce limit.
      The subsequent call to copy_page_range will walk the three level
      page table structure of the new process with non-zero pgd and pud
      indexes. This leads to memory clobbers as the pgd_index *and* the
      pud_index is added to the mm->pgd pointer without a pgd_deref
      in between.
      
      The init_new_context() function is selecting the number of page
      table levels for a new context. The function is used by mm_init()
      which in turn is called by dup_mm() and mm_alloc(). These two are
      used by fork() and exec(). The init_new_context() function can
      distinguish the two cases by looking at mm->context.asce_limit,
      for fork() the mm struct has been copied and the number of page
      table levels may not change. For exec() the mm_alloc() function
      set the new mm structure to zero, in this case a three-level page
      table is created as the temporary stack space is located at
      STACK_TOP_MAX = 4TB.
      
      This fixes CVE-2016-2143.
